Be it known that we, JOHN MITCHELL,

l VILLIAM WOLFE, and DENNIS PARKS, citie Zens of the iUnited States, residing in the city of St. Louis and State of Missouri,

have invented new and useful Improvements in HeeleBuilding Machines, of which the following is a specification.

1 The general object of the invention is to provide a heel building machinein the use I of which thelifts are pasted and assembled by hand, and then, by the action of the machine, formed, nailed and compressed,

and held under compression until the paste has set and the completed heel blank automatically discharged from the machine The invention is designed .inore particu-- larly for use in building decked'heels, and one of the salientfeatures thereof is the provision of novel means for automatically aliningthe lifts and'forming them. into the desired configuration of the heel blank before the compressing and nailing operation.-

Another important feature of the invention is the provlsion of means for enabllngth'e operator to readily assemble the lifts in i "the clear, and outside the'path of the down- V compiled lifts, and pressing the'heel' blank wardly-moving partswhich act to compress and nail together the compiledflifts, there byfacilitating the operation of building the heel blanksand minimizing the danger to the operator. In carrying outthis part 7 of the invention, we employ a pivoted-heelblank holder, which normally occupies an inclined position, its 'upperend. extending outward, ortoward the operator, and thee ing provided with -a gage-plate against" which the heel lifts arefali'ned, and which holder, by means ,of a; treadl, may be brought'to a vertical position 'for the'purpose of having the liftsnailed together and the heel blank pressed down into theholder by parts automatically operated by? the machine and placed in operation'by the movement of'theheel blank holder.

A further important feature of the invention is the provision of novel meansfor automatically compressing and nailingthe thus formedinto the heel blank holder.

A still further important feature of the invention is the: provision of a rotatable containerfor-supplying lifts of the desired size and in the required-order to the oper-f f ator. Preferably, two of such containers Fig. 8.

Th'ei numeral, 1 indicatesthe. base of the nria'chine on which is. supported the main frame 2,:thelower end of which rests upon and is secured to cross-beams 3 secured at 7 their ends to the side members base The numerale, Figs. 1, 2, and 10, indicates a heel-blank .holder which is' pivotally, mounted at Sin and between brackets 6, pro;

vided at the lower end of frame '2 at the 1 front side thereof. The holder 4 comprises a back plate 7, Fig. 14:, and a front or breast plate 8,'the back plate being preferably in the form of an angle-iron,,so :as to present a V-shaped recess for receiving the rounded portion. of'ithehee'l-blank, and the "breast plate 8 being flat so that the breasts of the heel-blanks may aline against it. Secured to either side of the breast-plate 8 and centrally thereof is a plate 9, which plates are connected byan integral yoke .9, having an arm 10 projecting rearward therefrom. To

the rear end of the arm 10 is connectedone f end of a coil spring 11, the upper end 'of which is secured to the frame of the inachine. Secured-to the.backplate 7 is a-plate 12 having on either side lugs 1 13 which rest upon the upper side of the yoke 9. The

numeral 14 indicates a-fmetal strap which embraces the breast plate .8 and is secured at its free end to the back plate 7. Mounted inthis strap is a turn screw 15, the end of which bears against the front of the breastplate 8. By means of the screw 15, the backplate 7 may be adjusted toward or from the breast-plate 8 to cause the holder to have the v proper size for'the heel-blank being formed.

Mounted at the upper end of the breast-plate 8 is a gage-plate 16, Fig. 11, having -a projection 17 at its upper end on itsrear side; The plate 16 isprovided with 'a' longitudinal slot 18through which passes a screw 19 having its head counter-sunk in thebreast plate 8. A guard 20 isapplied to thefront side of the plate 16, and a nut 21 on the screw' 19 holds the guard in! place and clamps'the .plate 16 in the proper adjusted position. In

- other'words, by the means described, the

plate 16 be raised or lowered accord ing to the height of the heel-blank being built the adjustment being such that when the last lift is applied its breast edge will engage under the projection 17 as clearly shownin Fig. 10. Mounted on the front side of the breast plate 8' is a spring arm 7 22 which has'aprojection 23 at itsupper-end extending inward over the upper end of the breast plate 8, and providedwith an inclined surface at 23 Screw19 passes through the lower end of the arm 22 and a washer 24 is inserted between said arm and-the guide.

plate 16. When the nut 21 is tightened the arm 22 will be clamped in position." In

proceeding according to my invention, and as shown byig. 10, as each heel-blankis compressed it is forced downward into'the .holder 4, that is to say, between the back plate 7 and the breast-plate '8, and in this movement the breast edge of the heel will force back the arm 22 by engaging the upper eased side oflth .p l and the i movement is so regulated that at itsterminationthe top. lift passesthe. project on 23 and the latter 'willfs ring'octane engage over the-breast portion of the top lift and thereby prevent the heel-blank from being forced upwardly bypexpansion ofits lifts, or of the lifts rof preceding heel-blanks 1 placed under compression, so tha'tth'e space for building-the heel blanks is always maintaineduniform, and alliofthe heel blanks are held' undercompressionlatter re-' suit is largely secured, however, by,fr ic-. tional engagement of the heel-blanks with the walls of theholder. g

In order to shape the heel-blank before it is compress'edfand nailedfweprovide a heel-forineriand:locate' the same in the line of movementof the upper end of the holder 4 containing. the assembled. lifts. Referring particularly to Figs. 3 and 4, the numeral 25 indicates a.-plunger,oi'1 the lower end of which; is secured the heel-former, indi cated generally by thesnumeral 26.: This heel-former comprises a cap-plate 27 whichis secured onr the' end of theplunger 25 by means'of a binding screw 28. Extending downward from either side at the rear of the cap plate 27 are-threearms, those at the sides being indicated by the numeral 29 and the arm at therearby the numera-l30. Each of, these arms isprovided with a central longitudinal slotin which a-series of plates 33. When' the'heel-blank has been'built 'onthe upper end of the'holder 4, the latter 'isthrown inward,;fo'rcing the lifts between the 'two setsoffplates-32 at the side of the I heel former 26 and againstthe' platesl33fat the rear thereof, thereby-forming 'orshapv ing' the heel blankflMounted on the front of the'heel-blank holder 1 are sheetmetal guards 34 which serve to protect the cloth- 2 ing of'the operator from contact withfthe paste which accumulates on the outside of the holder. The holder 4 is moved inward beneath the plunger 25 by means of a treadle 35, Figs. 2 and '10, which is secured substantially centrally on a rod '36 which is pivotally mounted at its "ends in bearings 37 secured on the side members of the base 1'. The .itreadle 35 is in the form ofa bellc'ranklever, having 'anupwardly extending arm 38'which is .pivotallyconnected to the,

outer end of a'pu'll-rod 39, the other end of said pull'rod'having a pintO which works "in a slot 41 in aslide-rod 42; the outer end of this rod is pivotally. connected at'43 to the holder 4 belowthe point'5 of pivotal connection-therewith with the frame. "The pin 40 also connects the inner end of the pull rod 39 with one arm 44 of a bell-crank lever 44, the other arm 45 of whichhas the lower end of -a coil spring 46 secured to its inner end. pivotally connected at 47 in opposite sides of: a hollow, semi-cylindrical member 48 provided at the lower end of themain frame The arm 10, heretofore referred to (see Fi 2 and 10), extends into'the casting, 48,

"and thespringll connected to said. arm

passes through an. opening in the upper side of the casting .48." By pressing down on the treadle 35' it will beseen that the rod will cause the lower end ot' the holder 4'to be thrown outwardand theupperend Of'SEHQl holder inward. The upper'end of the coil spring 46' (see Fig. 2) is connected to a collar 49 which is secured on a'vertic'ally disposedrod 50. The lower end of this rod passes through a bearing 51 provided in a bracket 52 secured to one of the frame'mem bers 3, and rests'upon'a' bearing, plate -53 which is secured on the end of the slide-rod 42. .A spring 54 is interposed-between the bearing 51 and acollar 55 fixedly secured on the rod 50. The upper end of the; rod

50 passes through-an openingaina'clip}56 and is PI'OVlClECl' with a roundedhead 58.

(See Fig. 8.) The numeral 59indicates a belt pulley which is loosely mounted on. a. drive-shaft 60, mounted in bearings 61 provided on the upper side of the frame 2. On

' the shaft .60 is a clutch-member 62 which is adapted to coiiperate withaclutch member 63 provided on the hub of the pulley 59.

T he clutch-member 62 is normally held out of engagement with the-clutch-member 63 by engagement of the head 681 with an annular flange 64pr-ovided on. the outer end of the clutch member 62., A coil spring 65 located inv the wall of the bearing61--op erates to force the clutch member162 into engagement with the clutch jmember 63 when the rod50 is pulled downward tov release engagement of the'head58 with the annular flange .64. A camfmember 66 is provided .on the -flange 64, which isadapted, by engagement with'the side of the head 58 to release clutch-member 62 from engagement with the corresponding member 63.

A coil spring 67 is secured at its 'lower end to a collar 68, fixedly secured on the. rod 50,

and at its upperend to the clip 56. This springipullsthe ro'd50 upward an dfholds it in the position; shown 1n E1gs'. 2 I The rod 50 is pulle'd downward]to relea'se the head v58 [from engagement fwith the flange 64 byth' actionof the spring 46.

As the treadle 35 is pressed downward the holder 4 will first be thrown into the vertical have" been moved downward to "extend the The said bell-crank lever is position and immediately thereafter, the rear end of the rod 42-will pass from'be. I

neath the lower endof the rod- 50. In this movement the'outer end of the armf45 will spring 46, which, when so extended," greaterpower than :the spring 67 and hence when the plate 53 passes from under the end of the rod- 50, saidrod 50 will be pulled. downward by the spring. 46 against the :resistance of said spring-.67, and the clutch member- '62 will be forced byf the spring"65 into engagement with the clutchmember 63. On'the forward end. of the V shaped portion 77 of the frame2: The lower end of the plungercarries a nailer 78 and is immediately over an abutment79 (see Figs. 4 and 8) secured tothe forward side of the plunger 25'at thelower end thereof,

said 'plunger 25, abutment 79, and heel former-.26 constituting a unitary member.

M ountjed'in the'abutment 7 9 isa nail holder 80 of any preferred constructiom th'e plate 27 being provided -with an aperture, 81', through which nails may pass. The numeral 82'indicates a nail guidemounte'd on a plate 83 which is secured on the front of the lower bearing 76 by a bolt 84. "Assuming, now, that'a' nail, 85, is in the nail'holder 79:, that the holder: '4 with the assembled heel-blanks; I 86 thereon, has beenmoved to the vertical position, shown in Fig. 10, by dotted lines, to bring the heel blanks within the'heel 3 former 26, and that the shaft 60 is rotating, the cross head 72- will cause the plunger75 todescend sothat the nailer 7 8will" enter 'g the nail holder; 80 'andfforce the nail therein into the" heel blank', and the lower 1 end of theplunger-75' will strike the upper end 'oftheabutmentf79 and thereby force the plunger 25 downward, compressing the heel-blank andforcing it intothe holder 4 and forcing preceding heel-blanks fpreviously "formed farther downward i'into ,ithe

The purpose of this construction is to per- 7 act as a cam which,'engaging the roller 88,

V will force the arm 87, plunger 25', rodj90,

and heel former. 26' downward, then the nailer 78-will drive the nail 85 into theheelblank, after which the lower end of the plunger will strike the abutment 79 (Fig.-

2, 3, 6, and 8, indicates a guard which is secured by means of a bolt 96andam nut 97-onthe front of frame 2, and is provided at :its front end-with; an upwardly turned lip; 98. fAs'the holder. 1 is thrown inward the topmost lift will engage the under side of the lip 98 and be guided thereby to pass under the edge-oftheplate 27. Without a this arrangement there would be danger of the top lift hitting the edge of said'plate.

is prevented by means of a brake shoe 99 @(Fig. 9) mounted on the upper'sideof the frame2 to bear .upon a friction disk 100 keyedon the shaft 60. A set screw 101,bearing'upon; the brake 99 regulates the degree of pressure of the'brake upon theffriction disk. Thereis no flywheel on the shaft 60,

and this brake mechanism prevents any tendency of the disk 69 to passflbeyond the deadcenter position, shown in Fig.3. x In order to enable ltl'le operator to select fto-be'usedin building up the heel-blanks, the following mechanism is provided: x

oneither side of the base. 1 are brackets, 102,

' which afford bearings,"1 03, for :two 'alining shafts'104e, each of which is. providedon its .outerend with a bevelpinion which is inimesh' with a-bevel gear 106, rotatably mounted." on astub shaft 107 securedimand. projectin upward from a side member of thefba'se'l; Each' of the gears 106 has'a hub 106 the bottom of which rests upon the top of a hub'107 of the b'racket102, aset screw 108 securing .said hub I107 in position on 1041s also. provided on itsinner end with a. bevel gear 108, only one of these being in mesh with a bevel pinion-109 which is secured on the end of a shaft llOsupportedin a bearing 111 on the rearside of frame .2. The rear end of the shaft has fixed Ithereon a pulley 112 and the rear endof the shaft 60 has fixed thereon a-pulley 113.

.Abelt 114: passes .overthe-pulleys 112 and Y 113 for driving shaft 110. Thenumeral' 115 indicates two lift containers and/as the the fixed stub shaft-107. Each of the shafts construction and operation ofjboth of. these is the same, the following description will be based on one of said containers. The

container 115 comprisesa circular bottom 116, a central cylindrical member 117 projecting upwardzfrom-the. bottom, an. outer circular casingllSand a series of radial partitions 119 extending'between thew'all of the cylinder 117 and the casing 118 and Which divide the container into' a series of. pockets 120. The 'lower'end ofthecasing' a.

118 terminates at'some distance above the bottomr116 and is inclinedinward.as'in-" dicated by. 121, thereby leaving an opening. 122 between thebott'om 1'16 and the lower end of the casing 118, through which lifts in the. pockets 120. may be removed by the operator. In thecenter of the bottom 116 is a bearing. 123, which receives the upper end bfthe shaft 107 and' 'is adapted to rotate thereon. The container 115 as'a whole, rests upon thetop ofthe bevel-gear'106,"a washer 124; being interposed between said gearand, the bottom of the container; As the'shaft 104 is rotated,the container 115will. beiro-' tated by frictional engagement with the gear 105 106, if'not prevented. Secured at' intervals around the bottom of the container 115, and

projecting slightly beyond the side thereof, are stops 125, Fig.15, which are adapted to engage the edge of a lever ;126,'which is pivotally mounted at its" inner end on'a pintle- 127 proj ectingupward from a bracket arm 128, which bracketarm is "secured at one end to thefront of the frame2. The opposite end of this bracket arm isbolted'to f and supports a paste pot 129iy1Numeral 130 indicates a plate which covers-a, greater 1 portion of. thispaste pot" and provide's,asf well, a table; The free end ofthe lever 126 Referringparticularly toFig. 1, located stops 125 are so positioned that when one of themf is in engagement with levcr 126' the container will be stoppedwith the 'center ofone of the pockets lying directly opposite the lever 126.
